Application of double sphere rubber joint in factory cooling water circulation system

March 17, 2025

In order to improve the reliability and safety of the system and reduce long-term operating costs, the customer factory decided to upgrade the cooling water circulation system.

After receiving the customer's inquiry, we communicated and confirmed with the customer repeatedly. According to customer needs, we determined the working environment (including temperature range, pressure level, medium type), displacement compensation of pipelines, installation distance and other factors, and finally decided to use double sphere rubber expansion joint with pressure ring design to ensure the safe operation of the system.

 

The following is our product information: 

Size: 12 inches (DN300)

Rubber material: EPDM

Length: Standard

Flange material: Carbon steel forging cold galvanized

Flange standard: ANSI 150LB

Gongyi Runda Pipeline Manufacturing Co., Ltd.

Our products have the following advantages:

First: The shock absorption and noise reduction effect is significant. Its elastic material characteristics can effectively reduce the vibration and noise generated by fluid flow.

Second: Excellent compensation performance. The spherical part of the rubber joint provides axial, lateral and angular displacement compensation capabilities, adapts to complex installation conditions, and can effectively absorb the thermal expansion and contraction effects caused by temperature changes.

Third: Strong corrosion resistance. Made of high-quality rubber materials, it has good chemical resistance and is suitable for a variety of media.

Fourth: Enhanced pressure bearing capacity. The design of the booster ring significantly improves the pressure resistance of the double-ball rubber joint, preventing damage to the joint due to excessive internal pressure.

Fifth: Simple maintenance, easy inspection and replacement, and reduced maintenance costs.

 

In this cooperation, our customer was very satisfied with our products and services. We will continue to adhere to our principles, customer first, service first, and provide high-quality pipe fittings to global users to make pipeline operation safer.
